B&A Gang Server... Redo

[tomozj]

Alright, some updates today.

- Added a fightclub mode. When /fightclub on is set (VIP level can, i.e. [BA] members), you can /challenge others to a duel. This feature will be extended in the future.
- Added a /setskin for administrators, format: /setskin [id] [skinid], or /setskin [skinid] to do it to yourself (it checks the number of parameters).
- Fixed the admin-PM-spam.
- Fixed the suicide death message.
- Added a /givegodall.
- Fixed proadmin outputs in adminmessages.
- Started work on an IP Class, half done.
- Planned in the next few days: fightclub win stat, saved to profile.

All good.
